Jenner & Block managing partner Terry Truax said: “London has been a very exciting opportunity for us. We really see London as the logical next step in the development of our platform and it pushes our front door to the whole of continental Europe.

“We’re looking to develop the platform. If you look at the size of our firm we have 10 lawyers in London, consistent to our commitment to grow. We’ll continue to build our platform in a very measured and deliberate fashion.”

Truax said Jenner & Block would replicate the approach it had taken with building its New York office, launched in 2005. There was a “targeted objective” to develop its platform in litigation, regulatory and investigations work, with transactional capability to follow.

But for the medium term, the focus in London was to “develop the disputes practice generally and international arbitration” alongside its investigations practice according to Truax.

The firm currently has five partners and a total of 10 fee-earners since its launch in London, with a focus on litigation.

Truax said that the firm was not “setting an arbitrary target at this point” with regards to headcount in London.

“We’re responding to what we perceive to be demands of our clients. We expect to see consistent growth,” he said.

Following the firm’s foray into Europe, Truax ruled out an office opening in Asia for now, despite saying that the firm “has a very strong robust Asia practice” with a lot of work generated from clients in Japan.
